I still go back to my Nemrod pneumatic air gun, one of which I gought new in 1974, a Mariner 2, wich still hunts just fine and I have only had to change the air once a year, I own 4 band guns and most of the time they stay home. Nemrod center grip trigger works best for me in our local conditions off Washington State USA. Problem is that Nemrod has gone out of business, so parts are getting hard to find. So now I'm trying to find out about Cobra spearguns made in Brazil, the model I'm interested in is the mini. Guys and Gals, I have been at this for a long time and I have heard them all about which type of speargun to use, I even made some up myself, and have decided that you should use what ever you want to drag around with you underwater.
